[Development] Is QMap Broken

Consider the following program, shouldn't the end() iterator place each key at the end of the newly created QMap. Instead, the keys and subsequent iterations are sorted (somehow). #include #include #include #include int main(int argc, char *argv[]) { QCoreApplication a(argc, argv);

Re: [Development] QVector: clear while keeping capacity

I think there should be a way to empty the vector without losing the memory. I would have said clear() should do that, but clear() says it releases the memory. martin From: development-bounces+martin.smith=theqtcompany@qt-project.org on behalf of M

[Development] QVector: clear while keeping capacity

Hello all, could it be that QVector changed its behavior in Qt5? I just noticed that resize(0) does deallocate memory, which is highly unexpected from my side. See e.g. this old thread where it was said to use resize(0) to clear a vector while keeping its capacity: http://comments.gmane.org/gm

[Development] QtQuick/QtGui/QtCore leak on exit

Hi everyone, I have a QtQuick app (that links against external MS MFC libraries) that triggers memory leak warnings on exit. I have run the test app through both Dr Memory as well as BoundsChecker (both in VS 2008) and both report memory leaks stemming from the QtQuick and QtCore libraries. The
